Install nodejs under Ubuntu 11.10

Step 1: Install the dependency package

1. Install Python version 2.6 or later (Ubuntu has been installed by default. You can use the pyhton-V command in terminal to view the Python version ). In Python 11.10, The Python version is 2.7.2 +.

My system displays:

Python 2.7.2 + (default, Oct 4 2011, 20:03:08)

2. install other dependency packages:
Sudo apt-Get install g ++ curl libssl-dev apache2-utils
3. Install the GIT tool:
Sudo apt-Get install Git-core
Step 2: Obtain the source code

Git clone git: // github.com/joyent/node.git
Wait until the download is completed. The size is 20 + M.
Step 3: Specify the compilation version, which is important!

1. First enter the folder for storing the downloaded source code (my current file directory is/home/jackqqxu /):

CD Node

2. Specify the migrated version:
Git checkout v0.6.8 (refer to: http://nodejs.org/dist)

node-v0.6.8.tar.gz 

This is very important. Some of the latest versions may cause NPM to be unable to download the corresponding package.

3. Specify the path for compilation and execution:
Mkdir ~ /Local
./Configure-Prefix = $ home/local/node
Make
Make install
Echo 'export Path = $ home/local/node/bin: $ path'> ~ /. Profile
Echo 'export node_path = $ home/local/node: $ home/local/node/lib/node_modules '> ~ /. Profile
Source ~ /. Profile
Step 4: Set Environment Variables

If you want to continue using the node command after the restart, you need to set the environment variable:
Run sudo gedit/etc/profile to open the configuration file. Add the following two lines at the end of the file:
Export Path = "$ home/local/node/bin: $ path"
Export node_path = "$ home/local/node: $ home/local/node/lib/node_modules"
Save and restart the system to make the settings take effect. Of course, you can also log out of the user here.
Step 5: Install NPM

Curl http://npmjs.org/install.sh | sh
Install the corresponding package as needed, such as express:
NPM install Express
If the command does not respond for a long time after it is entered, you can view the detailed execution information by adding the-verbose parameter, that is:
NPM install express-verbose
Generally, downloading fails for two reasons:
1. The network speed is too slow and exits upon timeout.
2. the node version is too new, and the downloaded package is not supported. (The solution is described in step 3 .)
Step 6: test the helloworld Program

Save the following code as a hello. js file.

1 2 3 4 5 6

var http = require( 'http' ); http.createServer( function (req, res) {    res.writeHead(200, { 'Content-Type' : 'text/plain' });    res.end( 'Hello Node.jsn' ); }).listen(8124, "127.0.0.1" ); console.log( 'Server running at http://127.0.0.1:8124/' );

Then run the following command:
Node hello. js
Start the service.
Open your browser and enter the address: http: // 127.0.0.1: 8124/

If Hello node. jsn is returned, the installation is successful! The effect is as follows:

I hope it will be useful to you. I have tested it myself.
